damage
1.1 Safety Precautions
This section explains the safety precautions to be observed during installation, wiring, operation, maintenance and
inspection.
Danger
⚫
Make sure the AC power supply voltage is the same as the rated voltage of the servo drive, otherwise there is a
risk of injury, fire, or damage to the drive.
⚫
It is forbidden to connect the input power cable to the output terminal, otherwise the drive will be damaged.
⚫
The drive cannot be tested for insulation withstand voltage, and the control circuit of the drive cannot be tested
with a megohmmeter.
⚫
The drive must be connected to the motor in the correct phase sequence, otherwise it will cause the drive to
malfunction or damage the drive.
⚫
Before trial operation of the servo motor, to avoid accidents, disconnect the motor load and run the motor alone.
⚫
Before the machine starts running, please make sure you can disconnect the power from the drive at any time
by the emergency stop switch.
⚫
It is necessary to set the corresponding parameters before running, otherwise the drive may not operate
properly or may have an unanticipated action due to the load.
⚫
Ask an electrical engineer to do the wiring, otherwise there is a risk of electric shock or fire.
⚫
Do not touch the conductive parts directly, and do not connect or short circuit the output line of the drive to the
housing, otherwise there is a risk of electric shock or short circuit.
⚫
Disconnect the power and wait 15 minutes before rewiring the drive, otherwise there is a risk of electric shock.
⚫
Contact current can reach 0.5mA, be sure to take reliable grounding measures, otherwise there is a risk of
electric shock.
⚫
During operation, do not touch the heat sink or external braking resistor, otherwise a scalding accident may
occur due to high temperature.
⚫
Please make sure to install overcurrent protector, leakage current protector and emergency stop device, and
make sure they are effective after wiring is completed, otherwise there may be danger of electric shock, injury and fire.
⚫
The leakage current of the driver may exceed 3.5mA during operation. Be sure to use reliable grounding and
ensure that the grounding resistance is less than 10Ω, and that the conductivity of the PE grounding conductor is the
same as that of the phase conductor (using the same cross-sectional area).
⚫
The components in the driver contain heavy metals, and the driver must be disposed of as industrial waste after
scrapping.
